TYPEWRITING IiIACHINE.

Application filed March 24, 1822.

To all whom it may concern:

Be it known that I, GEORGE A. SEIB, citizen of the United States, andresident of Ilion, in the county of Herkimer and State of New York, haveinvented certain new and useful Improvements in Typewriting Machines, ofwhich the following is a specification.

My invention relates to typewriting machines and more particularly totabulator mechanism.

The main object of my invention, generally stated, is to provide simpleand eflicient means whereby partsof the tabulator mechanism may bereadily assembled and mounted in the machine and may be readily detachedtherefrom when desired, thus re-g ducing the cost of manufacture andfacilitating detachment, replacement, and the making of repairs.-

To the above and other ends, which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts, andcombinations of devices set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicatecorresponding parts in the, different views.

Figure 1 is a fore-and-aft vertical view of the lower portion of animproved No. 10 Remington machine modified to incorporate my inventiontherein.

Figure 2 is an enlarged detail side view of a universal release bar andthe means for detachably mounting it in place, together with some oftheassociated parts.

Figure 3 is a transverse sectional view of the same taken on the line 33of Figure 2 and looking in the direction of the arrows at said line.

Figure 4 is a' detail perspective View of the universal release bar andsome of the associated parts.

I have shown my invention included in an improved No. 10 Remingtonmachine in which it may be readily embodied without materially changingthe structural features of said machine as they now exist, and have onlyshown so much of said machine as is necessary to illustrate theinvention in its embodiment therein. It should be understood, however,that the invention may be included in other styles of machines; for

Serial No. 546,316.

example, the invention may be included in an improved No- 11 Remingtonmachine, as Wlll hereinafter appear.

The frame of the machine comprises a .in which to mount such columnselecting stops, and as is customary in the improved No. 10 Remingtonmachine. The frame 3 is detachably connected to the frame of the machineby screws 4 which secure the tabulator frame to the base screws (notshown) 3 to the top plate. Upright stop actuating levers or members 5are pivoted to the tabulator frame, and coact with the selecting stops(not shown) to project them into the paths of the column stops onthecarriage. Each'lever 5 is pivoted at 6 to a forwardly extending link 7pivoted at its forward end, as at 8, to an actuating member or angularlever 9; This lever carries a forwardly extending finger 10 whichprojects through a slot in a key stem 11 carrying a tabulator 1 key 12at its upper end. Each stem works 1, and by other wh1ch secure the framein guide slots in the sheet metal guide plates I 13 and 14 fixed to thebase of the machine, and is limited in its movements in oppositedirections by felt pads a and b. The usual springs (not shown) areemployed to return the levers 5 with to normal position.

In order to effect a release of the carriage from the control of itsescapement mechanism at each actuation of a abulator key, I provide auniversal release bar 15 which extends across the machine in the pathsof the 7 rear edges 16 of the depending portions of' the levers 9. Thelevers 9 and the universal bar 15, as will hereinafter more pear, arepivoted on a pivot rod or cross bar 17, which in the present instance isin the nature of a rock shaft. A depressionof a tabulator key 12 iseffective not only toactuate the companion lever 9 and stop operatinglever 5, but also to swing the universal reand the parts connectedthereclearly aplease bar rearwardly. Two depending ears 18 on the bar 15have pivotally connected thereto, at 19, rearwardly extending links 20.The rear ends of these links are pivoted at 21 to arms 22 secured to arock shaft 23. Said shaft is pivoted for rocking movement at 2 1 tobracket arms 25 on the base of the machine. One of the arms 22 has aforwardly projecting arm 26 connected to the usual carriage releasingdevices, not shown.

In the improved No. 10 Remington machinev the rock shaft 17 is replacedby a be; fixed to the base 1, and on this bar is pivoted not only theuniversal release bar and the stop actuating levers but also two caseshift levers at opposite sides of the machine," such levers being unitedby connections extraneous to the center of the pivot rod on which theyare mounted. In the present construction I replace the fixed pivot rod,formerly employed, by a rock shaft 17, the latter being detachablymounted and pivotally supported at its ends by coned pivot screws 27threaded through tapped openings in the base, and held in position bylock nuts 28. Each end portion of the rock shaft is slabbed off onopposite sides at 2-9 to provide-a projection 30 which is angular incross section; a shoulder being formed where each projection joins theshaft. Each of these projections 30 is received and fixed in acorrespondingly shaped opening in a case shift lever 31, pivoted at itsrear end, as at 32, to an upwardly extending link 33 connected with theusual shift rail. Each lever 31 carries a lateral projecting pin 34:grooved to, receive the hooked end of alink 35. The rear end of each ofthese links is connected to one end of a contractile spring 36 connectedat its other end to a pin 37 fixed to the base. The force of thesesprings tends to counteract the weight of the platen. 7

It will be seen that the rock shaft 17 forms a rigid connection betweenthe two case shift levers along the pivotal axis of said levers wherethe connection is most effective to cause the levers to move together,the fixedly connected levers and shaft constituting in effect a caseshift frame.

In accordance with my present invention I provide means whereby thelevers 9 and the universal release bar 15 may be readily mounted inplace for pivotal movement on the rock shaft 17. Thus at differentpoints throughout the length of the rod I form circumferential bearinggrooves 38, the number of such grooves depending on the number of levers9 employed. The two end grooves 38 receive hook-like bearing members 39,each formed integral with an upwardly extending supporting arm formed asa part of the bar 15 at an end thereof. The width of each groove 38preferably corresponds substantially to the thickness of the member 39which receives a bearing therein. In this manner the members aremaintained spaced apart and are prevented from displacement along therod 17. Each part 39 may be readily hooked over the rod 7 and seated inits bearing groove 38, and

in cross section, and is adapted to straddle.

and embrace both sides of the member 40 that carries it. The sidemembers 41 of the latch are united at 4.2, and are spaced apart at everyother portion thereof so as to receive the associated arm. 10 betweenthem and enable the latch to turn on a pivot 43 (by which it isconnected to. the arm) from the full to the dotted lineposition in Fig.2,

or vice versa. The upper edge 4A of each slde plate or member 11 iscurved concentrically with its pivot 13, and when the latch is in thelocking position said edges are ad acent to the body. portion of the rod17 on opposite sides ofthe companion groove 38. This prevents the member39 from moving up off the rod and out of its bearing groove.

In order to prevent accidental displace ment or the latches from theirlocking position, I have provided each latch with a rounded projectionor detent 45 struck up and extending inwardly from one side of the latchand adapted, when the latch; is in the locking position to seat itselfin a holei or depression 46 in the arm 4L0. Each of the lovers 9 in alike manner is provided on its upright arm with a hook like bearingportion 4? adapted to be hooked over the rod and seated in a bearinggroove 38 therein and to receive pivotal n'lovement thereon. If desired,each lever 9 may be provided with a relatively movable retaining latch41 of the character described, but this is a deemed unnecessary in thepresent instance since the construction and the relative arrangement ofthe parts are such that there is little liability of the levers beingaccidentally detached from their supporting rod. However, the levers mayeasily be mounted in place or disconnected when desired, thusfacilitating assembling the ma chine and reducing cost of manufacture.

I have shown the usual shift lock key a8 in addition to a shift key l9on thelefthand lever 31. The key 48 is carried by a locking member 50pivoted at 51 to said.

lever 31, and carries a hook-like engaging member 52 adapted to engagethe co-operafive fixed member 53 on the base of the machine.

In the present instance I have shown five tabulator keys 12 and fivelevers 9 controlled thereby for controlling a corresponding number ofstops, as in the improved No. 10 hemington machine, for selectingcolumns. It should be understood, however, that a greater number oflevers 9, say ten, may be mounted on a bar 17 with more bearing grooves38 therein and a corresponding number of keys 12 and levers 5 may beprovided to control denominational selecting stops for denon'iinationalselection, as in the No. 11 Remington machine, instead of columnselection, as in the No. 10 machine.

Various changes may be made without departing from my invention asdefined in the accon'ipanying claims and certain features thereof may beemployed without others.

lVhat I claim as new and desire to secure by Letters Patent, is

1. In a typewriting machine, the combination of a cross bar having aperipheral bearing groove therein, a depending arm having a hook-likebearing portion seated in said "lplieral bearing groove, ant, retainingmember carried by and straddling said arm am; coacting with theperiphery of the shaft outside and on opposite sides of saidperiphgroove to prevent a displacement of the transversely of the crossbar, said reing member being movably mounted on arm for movement intoand out of reg position, whereby the arm may be readily dismounted whenthe retaining member is open by a displacement of the arm transverselyof the cross bar.

2. In a typewriter or like machine, the combination of a cross barhaving a series of peripheral grooves cut therein at different points initslengt-h, and a series of de pending arms each having a hook-likebearing portion closed at its upper side and open at the bottom andseated in one of said grooves for support and pivotal movement on thecross bar and prevented from displacement along the bar by the walls ofits groove, the arms being thus detachably mounted and maintained spacedapart on said bar, one or more of said arms carrying an independentlymovable retaining member movable to open and close the mouth of thehook-like bearing thereof, to prevent the associated arm from beingdetached or enable it to be detached depending on the position of itsretaining member.

3. In a typewriter or like machine, the combination of a cross barhaving a series of peripheral grooves cut therein at different points inits length, a series of depending arms each having a hook-like bearingportion closed at its upper side and open at the bottom and seated inone of said grooves forv support and pivotal movementon the cross barand prevented from displacementalong the bar by the walls of its groove,the arms being thus detachably mounted and main tained spaced apart onsaid bar, one or more of said arms carrying an independently movableretaining member movable to open and close the mouth of the hook-likebearing thereof, to'prevent the associated arm from being detached orenable it to be detached depending on the position of its'retainingmember, each retaining member comprisin a sheet metal device folded intosubstantia ly Ushaped formation in cross section and straddling thearm'by which it is carried, and detent means for holding said retainingmemlber against accidental displacement from its active position whereit closes the mouth of the bearing and prevents an upwardly.displacementof the as sociated arm. 1

4. In a typewriter or like machine, the combination of a key actuatedrock shaft having a series of circumferential grooves cut therein, and aplurality of depending arms each having a hook-like bearing portionclosed at its upper side and open at the bottom and seated in one ofsaid grooves to detachably support its depending. arm and pivot it onsaid rock shaft, one or more of said arms having a relatively movableretaining member thereon adapted to open and close the mouth of theassociated bearing and prevent an upward displacement of the companionarm from the shaft.
